Argentinian left-back Emiliano Insua has left Liverpool to join Sporting Lisbon on a five-year deal.
Insua became surplus to requirements at Anfield following the arrival of Jose Enrique from Newcastle.
The 22-year-old said he was looking forward to a new challenge in Portugal, and told Sporting's website: "I am delighted to start training and playing here."
He added: "Sporting is one of the big Portuguese clubs and is recognised for having top players.
"The club is always looking to win titles. I will give everything for Sporting."
Insua joined Liverpool from Boca Juniors, initially on loan, in January 2007.
He made 44 appearances for the club but was sent out on loan to Galatasaray last season.
